Model 100 Spreader

Postby GunnerP » Tue Jan 01, 2019 11:38 am

I'm a new member here. I own a model 100 manure spreader. It works great most of the time, but the last time I used it the chains that advance the manure to the rear of the spreader were real erratic in pulling the load to the rear. I drove and drove and sometimes they would advance a smidge and then other times it would advance 1/3 of the load in a short distance. Any hints would greatly be appreciated.

So far, Paul and Ringo have arrived. John and George were supposed to follow ages ago, but apparently have gone awol. Long story.

First thought: is everything lubed properly?
Under the right side fender, something isnt right with the cam follower or ratchet mechanism.
There’s a ratchet at both the top and bottom of the gear, each with a spring, plus the cam follower has a spring.
If any of those springs are broken or anything rusty enough to not move freely, you’ll get that erratic action.

Here’s a photo where I’ve highlihted the two parts of the ratchet mechanism and the pivot for the cam follower. My guess is your cam follower is binding.

Besides what Tim said, I've seen the dogs of the ratchet assembly bent so that they no longer properly engage the teeth of the ratchet wheel. It usually happens to the one on the bottom, and frequently when the machine is operated while the apron chain is frozen in place.

As Tim mentioned, I'd also be suspicious of a pawl spring having broken. In addition, there is small solid roller that moves up and down as the cam revolves when the axle turns. If the roller is worn down it can cause that problem. Try pulling the lever down past the last notch and see if that helps. If you click on "quick links" upper left, then "PDF Manuals", then "Farmall Cub", then "Cub attachments", then "Spreader, carrier,..."; you'll find a manual for the 100.

Thanks for the feedback! Everything is lubed well. I'll check on the pawls and their springs. I hope nothing is broken as I did a quick search on the web yesterday and did not see too many parts available. I found the manual yesterday as well. Thanks again for your assistance.

GunnerP I have a parts spreader, if you need parts.
